Very much recommended!
This is only one of the line of YoLink products that we purchased and all of them are very reliable, easy to operate and recommended! This one I'm using as alert for sump pump. Hi availability, long range coverage and reliability. Various scenarios can be programmed and alarms will be received. Shareable monitoring.

Don't buy refund still outstanding £100
They do not understand a word of English ,I feel I have been transported to a hawkers stall in my home country. I had to call call to get a refund Products are equally unreliable as the people behind it. Quick money

Consider the cable extension for a washing machine
Installed this around/under our washing machine. It was a bit difficult to hang the sensor and then string the cable in the tight space around the washer without moving it. The cable was long enough to run around the back of the washer where the water hoses are attached. It might be a good idea to get the add-on cable so we could extend it to the front of the washer as well. Overall, I'm happy with the YoLink system: easy to set up, attractive, effective, and reasonably priced.

Drill holes to find water
I brought this for my daughter and her husband who had a water leak from somewhere. I thought they would hold it against the wall and it say when it found it. The end has to come into contact with water so you have to drill holes into the wall so you can put the sensor into it to touch the water. They said it was helpful but it wasn’t what I thought it was going to do.
